How about singing this song to it's original tune (now the tune of the US Nat'l Anthem) in English or even in Spanish? Now wouldn't that be confusing? What would the English-only advocates of the US Nat'l Anthem say to that?

What did I hear on NPR news today about a new bill introduced (or to be introduced) in US Congress to mandate the singing of the Nat'l Anthem only in English?
